The families have donated more than $1 million and plan to seek contributions especially from other wealthy people, including those without personal connections to any service members.

Philip Green, president of PDG Consulting, a health-care consultancy, and his wife, Elizabeth Cobbs, chief of geriatrics at the Veterans Affairs Medical Center in Washington, D.C., joined with their friends Glenn and Laurie Garland and with the Jim Stimmel family to create the fund, Mr. Green said in an interview with The Chronicle.

Mr. Green and Ms. Cobb have donated $600,000 to start the fund, and the Garland and Stimmel families have each contributed $250,000.

Michelle McCarthy, a spokeswoman for Iraq and Afghanistan Veterans of America, said the fund will focus fundraising appeals on people who can give at least $250,000, but will accept donations of any size.

The announcement of the fund comes at a crucial time. A recent Chronicle article reported that many charities that serve veterans are desperate for money.

The impetus for the Veterans Support Fund came from Mr. Green and his wife, who said they realized how fortunate they were that their three grown children were not involved in the wars and came to believe that soldiers and their families are owed a special debt.

“The message we’re trying to communicate to these families is this is a moral obligation rather than a decision to give a charitable donation,” Mr. Green said. “This is different because you really have a moral obligation to give, you actually owe [military families] money.”
